Does anyone here have experience with those types of crystals?
Brookite, Natrolite, Phenacite and similar crystals have a noticeable vibrational feel to them though it typically takes awhile until people adjust to their intensity.
There are some obvious differences between them as well but all obviously boost telepathic ability/function with extended use. You could even go further and combine them with things like rhodizite to amplify them more.
Does anyone here have experience with that kind of thing?
I saw your video on Moksha and the black hole entity, it was very cool.
Have you tried communicating/pinging similar beings (not per se negative ones) with the energy centers above your head? A lot of ETs use telepathy/communication mainly from 6th chakra awareness, but it's also possible to integrate communication with centers above the head at the same time even though the format of the information is different.
